Worse still, according to the report, which covers airport and airline activity in the month of June, the overall performance of Chinese airports has become worse in the past half year.

At the bottom of the list of major world airports is Beijing Capital International Airport. In June, just 18.3% of flights from the airport left on time.

Around 42% of flights from Beijing suffered delays of 45 minutes or longer.

Second worst on the list is Shanghai Hongqiao International Airport. Just 24% of its June flights departed on time, compared with a 38.9% on-time departure rate six months ago.

"None of China's provincial airports surveyed by FlightStats -- including Guangzhou, Kunming, Nanjing, Chengdu, Changsha and Urumqi -- could manage to get half of their flights on time," according to a story in the South China Morning Post.

Top performing large North American airports were in Honolulu (86.29%), Vancouver (86.18%) and Salt Lake City (85.55%).

Alaska Airlines had an on-time performance of 86.8%.

Top performing large European airports were in Amsterdam (83.52%), Munich (83.35%) and Vienna (82.15%).

China's major airlines also fared poorly compared with regional and global counterparts.

"Major international airlines on average delivered 75.85% of their flights to the arrival gate within 15 minutes of schedule in June, down from May's 80.70%," according to the FlightStats report summary.

Top overall Asian performers were Air Busan (96.77%) and J-Air (95.64%).

According to the South China Morning Post, the poor performance of Chinese airports and airlines is blamed on "excessive military control of airspace and poor urban planning."

"Nearly 80% of China's airspace has been reserved for military use. In other countries, such as the U.S., the situation is exactly the opposite," according to a Hainan Airlines official quoted by the SCMP.
